4 TEN OAKS NURSERY AND GARDENS 
have to put up with. White-fly, Lacebug, Leaf Minor, 
Scale, Thrips, and Red Mites—are the most common 
insects to contend with, and these can be controlled by 
spraying just as soon as the danger of over-night freez- 
ing has passed and before plants have blossomed. The 
material to use for this purpose is 14% teaspoons 20% 
Vapotone plus 14% teaspoons 25% D.D.T. emulsion 
mixed with one gallon of water or the all in one ma- 
terial Pest-Hex available from us P. P. 1 lb. 2.25 P. P., 
5 lb. 8.65 P. P. A second spraying should be applied 
after blooming or June 15, a third around July 5, and 
a fourth may be desirable around August 5. Use a force- 
ful mist and direct under the leaves. Chlorosis or Yel- 
lows—Dissolve one ounce Epsom salts in two gallons 
water and sprinkle over the plant and soil thoroughly; 
two weeks later use one ounce of iron sulphate to two 
gallons of water the same way, and you will have your 
plants back to a normal green, if you have kept them 
well fed and watered. Fungus Diseases—Bordeaux or 
Cuprocide mixtures or Pest-Hex at ten-day intervals 
take care of mo t of the fungus. 
AZALEA APPRECIATION—If you pick your aza- 
leas in the nursery according to their mature growth, 
you may have many uses for them. They may be used 
as foundation plantings, naturalistic plantings in light 
woodland areas, bank or hillside plantings in mass, 
hedges or boundary plantings, and footings to ever- 
green or flowering shrub plantings. Planting in mass 
always gives a better effect. H. H. Hume says in his 
latest publication, “While azaleas are exacting in their 
culture requirements, they are not difficult to grow if 
their needs are met. Careful attention to details at 
planting time will make their culture easy in after 
years. They may be transplanted to gardens in any 
size from plants a few inches to several feet in height. 
Their beauty of foliage, flowers, and in many varieties 
their spicy scent sets them aside as superior plants for 
the house. For the same uses branches in flower are 
most desirable, and those who are fortunate can have 
supplies from their own gardens. 
“Under conditions that suit them, azaleas are long- 
lived plants. . .. There are specimens still in fine 
condition that were planted in 1848. They have added 
to their stature and bloomed through the years to make 
each season a scene of great beauty. Many genera- 
tions of plants of other kinds have come and gone in 
other gardens in the century of their growth. Azaleas 
are plants of a human-lifetime span and more. 
“Many commonly used broad-leaved evergreen shrubs 
are valuable mainly because they are evergreen, but in 
addition to holding their foliage throughout the year, 
persistent-leaved azaleas are unsurpassed as flowering 
shrubs. Any garden well designed and furnished with 
azaleas immediately is lifted out of the commonplace. 
There are few uses to which other broad-leaved shrubs 
are adapted that cannot be filled as well by azaleas.” 
Because of a complete crop failure on some 
varieties listed in former years; the old timers 
will miss them in this year’s catalog. We are 
still testing them all and if they prove their 
worth will be back in this listing at a later date. 
Home Grown. Unless otherwise noted all 
plants offered in this list or at our nursery are 
grown by us here in Howard County at an ele- 
vation of 545 feet. We buy in no stock from 
distant points for resale thus giving our cus- 
tomers every possible advantage of getting a 
top quality plant that is acclimated. 
Landscape Design. We would also like to share 
our twenty-eight years’ experience in land- 
scape problems with you. Our Nursery tries to 
take a personal interest in adding to, or replant- 
fag your home. Pencil sketch and estimate 
furnished with no obligations for this season’s 
planting. We grow many different varieties of 
Evergreens, Flowering Shrubs, and Shade Trees 
right here at Ten Oaks. Phone Clarksville 
650-J, or visit us near the village of Clarks- 
ville in Howard County. It’s just off Route 29 
at the above village, halfway between Balti- 
more and Washington. Sign there will direct 
you. We do our best to make visitors welcome. 
Many say it is worth the trip to Ten Oaks 
just to see the Display Gardens. 
We have many varieties of Azaleas and other 
plants that we do not list because the quanity 
does not warrant the space. 
This is the only catalog we issue. All other 
items are sold from the Sales Garden or used 
in Landscape Design work. 
The New Pest-Hex. We used it this season 
with very good results so we can reccommend it 
to you. We are handling it for the convenience 
of our customers in 1 lb. and 5 lb. packages. 
Write for pamphlet on Pest-Hex if you didn’t 
receive one. 5 Ib. Pke. 8.65 P.P.

The Glenn Dale A\zaleas 
These new and beautiful hybrid azaleas were origi- 
nated by Mr. B. Y. Morrison, and introduced by The 
Division of Plant Exploration and Introduction De- 
partment. 
We say, a greater piece of work has never been done 
for the thousands of people who love azaleas but be- 
came discouraged from growing them after a severe 
cold night followed by a hot day in the late Fall or 
Spring killed many of their pets.
